What happens during the decomposition of refrigerants like R-22 when exposed to an open flame?

When refrigerants like R-22 are exposed to an open flame, they undergo decomposition, which leads to the production of toxic gases. Specifically, when heated to high temperatures, R-22 can break down into hazardous compounds, including hydrogen chloride gas, phosgene, and other harmful byproducts. These toxic gases pose serious health risks, including respiratory issues and potential long-term effects.

It’s important for those working with refrigerants to understand this risk, as it underscores the necessity of proper handling and storage procedures to prevent exposure to such hazards. The generation of toxic gases during combustion clearly highlights the dangers of using refrigerants improperly, particularly in environments where flames or high temperatures are present. This emphasizes the critical safety procedures that must be enforced when working with refrigerants in any capacity.
